BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a portable work and storage container, and more particularly to the joint structure for the portable work and storage container, wherein the joint structure not only enhances the rigid structure of the portable work and storage container but also allows the portable work and storage container to be disassemble for storage and transportation.

2. Description of Related Arts

A storage container, such as a cargo, is considered as one of common tools for transporting a load over land, sea, or through the air. A conventional storage container comprises four sidewalls, a top wall, a bottom wall, and a frame structure supporting the walls to form a rectangular shaped container. Since the load is relatively heavy, generally more than thousands pounds, the storage container must be transported by lifting machine from one spot to another spot. Thus, the frame structure must be rigid enough to support the heavy load.

Instead of carrying the load, the storage container is recently used as a portable work container. For example, the portable work container is set up when the building is under construction such that people are able to temporary work in the portable work container. A mobile home can also be built by the portable work container. No matter what the storage container is set up as a storage cargo, portable work container, or the mobile home, the frame structure must be strong enough to withstand the environmental influence, such as wind or rain, and to protect the load or people inside the storage container.

In addition, the storage container requires lots of space for storage or transportation even though the storage container is empty. In other words, the storage container cannot be disassembled for storage and transportation purposes. It is because the frame structure must be formed in one piece structure to maximize the strength of the storage container. Therefore, when the storage container is empty, the mover can only carry one storage container at one time to transport the storage container from one place to another place.

An improved storage container includes a joint to disassemble the frame structure such that two or more storage containers can be transported at the same time. However, the joint, especially for the movable joint parts thereof, will substantially weaken the overall structure of the frame structure because the stress will be created around the joint. Therefore, it is a conflict between the strength enhancement of the storage container and the collapsible feature of the storage container for easily transportation. The existing storage container obviously cannot achieve the current needs of the users to provide both strength enhancement and collapsible feature for the storage container.

Each of panel lockers 34 is an elongated screw having a length longer than the total thickness of two overlapped connecting panels 33, such that the panel locker 34 is extended through the mounting holes 311 to detachably couple the two connecting panels 33 with each other. Accordingly, the assemble/disassemble operation of the shaft holder 313 is relatively simple and easy by screwing/unscrewing the panel locker 34 with the connecting panels 33.

According to the preferred embodiment, each of the reinforcement channels 300 has a non-circular cross section, wherein each of the reinforcement shafts 32 has a non-circular cross section corresponding to the reinforcement channel 300 such that when the reinforcement shaft 32 is disposed in the respective reinforcement channel 300, the reinforcement shaft 32 is retained to prevent a rotational movement within the reinforcement channel 300. As shown in FIGS. 2 to 4, each of the reinforcing channels 300 has a square cross section while each of the reinforcing shafts 32 also has the corresponding square cross section to fit into the respective reinforce channel 300.

Accordingly, each of the reinforcing shafts 32 is made of rigid material such as steel or even concrete, wherein each of the reinforcing shafts 32 form the main supporting pillar of the portable work and storage container of the present invention. Each of the reinforcing shafts 32 can be a hollow shaft or a solid shaft. As shown in FIG. 5, a top side of each of the reinforcing shafts 32 is biased against the top retention frame 21 when the upper portion 321 of the reinforcing shaft 32 is received in the upper socket 310 of the upper joint 311. Likewise, a bottom side of each of the reinforcing shafts 32 is biased against the bottom retention frame 22 when the lower portion 322 of the reinforcing shaft 32 is received in the lower socket 320 of the lower joint 312. Therefore, each of the reinforcing shafts 32 is formed the main pillar to support between the top and bottom retention frames 21, 22 and is held within the respective reinforcement channel 300.

It is worth to mention that when the top and bottom retention frames 21, 22 are coupled via the joint structure 30, the reinforcing shafts 32 are rigidly supported between the top and bottom retention frames 21, 22 to enhance the strength of the portable work and storage container. In addition, the top and bottom retention frames 21, 22 can be detached from each other via the joint structure 30 such that the portable work and storage container can be collapsed to form an impact size as shown in FIG. 5.
